1. Florescence of sunflower

Sunflowers are usually sown from February to April every year. It takes about 60 to 80 days from seed development and maturity to flowering. According to the growth cycle, the flowering period of sunflowers is in summer, which happens to be the hottest July and August. At this time, sunflowers bloom one after another, as if urging each other

However, if some sunflowers are sown late, their flowering will be delayed. Because sunflowers have strong vitality and can be sown all year round, it is also common for them to blossom in May or October

2. When does Sunflower Bloom

Because the planting time of sunflowers is inconsistent, the flowering season is also inconsistent. But most of them bloom in July and August every year, that is, summer. In addition, some open in late spring, early summer or early autumn

3. Method of prolonging flowering period

Delay pollination time: sunflowers generally wither after the beginning of fruiting, and if you delay pollination, you can delay the time of fruiting. Just don't let insects such as bees and butterflies get close to sunflowers when they bloom

Ensure sufficient light: sunflowers grow in the sun. They must have sufficient light to grow better. The flowering period should ensure sufficient sunshine, which will make its color more bright and the flowering time will be relatively prolonged

Control the amount of watering: sunflower itself does not like water, so we must pay attention to control the amount of watering during flowering. Watering too much will make it grow faster and speed up the end of flowering. On the contrary, it will make the flowering period relatively longer

Pay attention to keep it warm: some sunflowers grow late and bloom later. At this time, you need to keep it warm. Warm environment will make it bloom longer, and too low temperature will make the plant wither
